ALLOY. 1

Ho Drawing.

.This invention relates'to alloys, particu larly alloys of lead, and Willa-be fully -under-. stood from the following description. It hasbeen suggested heretofore that alloys be made up of leadand sodium, in which the-composition proportionsshould be 86% on less of lead to 14% or more of sodium.

'ViTe" have found however that allo -'s made of more than 86% of lead and less t Ian 14% of sodium exhibit quite definite properties';

and 'an alkali metal, which comprises elecas the Composition aportions of 90% lead and of substantially and in particular preaches the pro 10% sodium. n alloy 90% by'weight of lead and '10%-by weight- 10 of sodium corresponds to a' compound NaPb and-is especially reactive to halogenhydro carbon compounds, where. desired to produce hydrocarbon compounds of lead.-

In reparing the alloy, the lead may be inelte in a suitable container and the. so-

dium .added.

rived from sodium chlorid and the lead bc-- ing provided in metallic state-or an'electrolyzable compound. The molten alloy may be directly suitably subdivided in an inert atmosphere, or'it may be cast in ingots as,

' prises clectrolyzing a SOilllllll compound in ,amount adapted to furnish the required proportion of sodium, while in the presence of desired. 1

While the invention has been describedby reference to certain specific details, it will be understood that this is illustrative and not limitative, and changes may be made within the spirit and scope of the invention.

lVe claim:

1. The process of making an alloy of lead 40 and sodium, which comprises elcctrolyzing To avoitl oxidation is ad- I visable that operations be carried on in an inert atmosphere, nitrogen for example, be-:j

a licatio filed ma :0, ma serm- 10.16883 sodium chloride to produce molten sodium and combining the sodium with lead in the electrolytic bath, while preventing access of xyg n.

2. The'proccss of making an alloy of lead and sodium, which com r;ses electrolyzing sodium-chloride to protfilce molten sodium andgombining thesodium with lead in the electrolytic bath.

i 3. -The procsss of making an alloy of lead trolyzinga suitable alkali metal salt to produce the alkali metal and combining the same with lead in the electrolytic bath in the substantial absence of other alloying metals.

' 4. The process of making an alloy of lead 'and an alkali metal, which comprises simulfused bath under conditions to form an alloy of the metals in the substantial absence of other alloying metals.

(5. The process of making a binary alloy containing about 90% by-weight of lead and10% by \vcight of sodium, which comlcadin alloy-forming condition.

7. An alloy comprising substantially 90% weight of lead and 10% by weight of sodrum.
